The present invention has for its objectvto provide improved means forsupporting the brake beams of railway cars, and the lnvention is Vapplicable to what are commonly known as third and fourthpoint supports.In supportsiof this character, it is necessary to sustain thevtensionmember side of the brake beam byv a spring track or tracks having aninclined portion or portions to gu de the brake beam as it is moved backand forth in'applying and. releasing the brakes; and it is alsocustomary to interpose a shoe or shoes betweenthe tension members orportion of the brake beam and the supportingsprlng track or tracks. Myinvention is designed particularly to provide a simple and efiectiveconstruction of shoe or carrier for susta ning the brake beam upon itssupporting track or tracks. The invention consists in the features ofnovelty hereinafter set forth, illustrated in the accompanying drawings,and more particularly pointed out in the claims forming part of thisSPGCifiCatIOII. In-the drawings: 1 7 Figure 1 is a plan view showingthecentral portion of a brake beam embodying my invention, and showingalso a part of the adjacent spring plankand spring track.

Referring to the embodiment ofthe invention shown in Figures 1, 2 and 3of the drawings, 1 designates the spring plank of'a' car truck -fromwhich projects a supporting spring ,track 2 that is suitably attachedthereto and has the usual inclined end portion for sustainingand guidingthe brake beam." The brake beam is shown vcom prising the usualcompression member 3 and; tension member 4, between which'extends thestrut or lever support 5. V 1

Between the spring track 2 and'brake beam is interposed myimproved shoeof carrier that may be made as a drop forging or a mallea'ble' casting.Asshown, this shoe or carrier has a rounded lower portion 6 adapted toride upon'the spring track 2, and the upper portion of the shoe orcarrier is formed with upstanding lugs 7 and 8 at the ends thereof;

The shoeor carrier is of such length as to afford a space or seatbetweenthe lugsat the ends thereof to receive the end of the strut 5 that isnotched or channeled to admit the tension member 4ofthe'brake beam;andth'e lugs 7 and 8 ateach end of the shoe or carrier are'spaced aparta sufficient distance to permit the tension member 4 to passtlierebetween when the shoe is to be applied to the strut and tensionmember.

By reference to Figure"2, it will'be seen that when the shoe is placedupon the end of the strut, the strut will rest upon the upstandingledges'or portions 6 and 6 of the bottom portion of the shoe or carrier,while thetensionimember i will rest within the seats formedv between-thelugs 7 and 8. lVhe-n'the parts have been thus assembled,

the upper ends of the lugs 7"and 8 will-bebe nt (from the positionjshownby dotted lines,

Figure 2,) inwardly and over'the tension member 4, and be forcedfirmly'there against, thereby rigidlylholding' the shoe or carrier inpositionjwith respectto the strut and tension member. .The upstandingcent the bottoms of the upstandinglugs and w v portions 6 and 6 of theshoe orcarner ad a-' .lengthwise of the track, but may move alsotransversely thereof, to a limited extent incident to the endwisemovement of the brake beam in practice. The upstanding ledges 6 and 6afford a firm support for the outer end of the strut 5 when the guardlugs 7 and 8 are in closed position, and all danger of the turning orrocking of the shoe or carrier with respect to the strut 5 and tensionmemberis avoided. 1 y

In the form of the invention illustrated in Figures 4cand5 of thedrawings, the shoe or carrier issimilar in construction to thatheretofore described; but instead of'being provided with two lugs ateach end, the shoe or carrier,,inthis modified form of the invention, isprovided at each end with a single long bendable lug 7 The end walls 10of the shoe or carrier shown in Figures 4 and 5 are spaced a suflicientfdistance apart to admit the strut 5 that will rest upon the transversewalls 10 and 10 and the upper edges of the end walls are formed withshallow seats to receive the tension member l. When the shoe or carrierhas been placed upon the strut and tensionmember, the lugs 7 a will bebent from the upstanding position (shown by dotted lines-Figure 5,) downand around portions of the tension member at the sides of the strut andwill rigidly clamp the shoe or carrier in position thereon.

In the form of the inventionshown in Figures6, 7 and 8, the shoe orcarrier is shown as provided with an inclined flat lower portion 8adapted to rest upon the spring track and with upstanding end walls 9and 10 spaced apart to receive the end of the strut 5 and having seatsto receive the portions of the tension member at each side of the strut.U standing lugs 12 and 13 are provided in this modified form of shoe orcarrier, and when the shoe or carrier is in position upon the strutandtension member, the lugs 12 will be bent downwardly upon the tensionmember, while the lugs 13 will be bent downwardly over and upon the endof the strut, as clearly shown in the, drawings.

In Figures 9, 10, 11 and 12, in which my invention is shown as appliedto a shoe or carrier fora fourth point support, the lower portion 14 ofthe shoe or carrier which is adapted to ride upon the spring track isformed at an angle to the upper portion that receives the brake beamtension member 4;.

A In this construction, the tension rod rests in seats in the end walls15 and 16, these seats preferably having flattened portions 17 whichenter notches in the tension rod so that the shoe cannot turn onthe rod.The shoe is clamped on the rod by bending over the integral lugs, 19, 20and 21 as shown, these lugs being disposed angularly with respect to thelower portion 14: of the shoe or carrier.

The details of construction above set forth may be varied withoutdeparture from the invention, and features of the invention may beemployed without its adoption as an en tirety. V

,Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

A brake beam support comprising the combination with a brake beamand a supporting track, of a shoe interposed between the beam andtrack,- said shoe havinga lower portion resting upon the track in amanner free to move lengthwise and; transversely thereof, and having anupper portion adapted to receive the tension rod of the brake beam, andprovided with a guard at each end of the shoe adapted to extend over thetension rod of the brake beam and retain the shoe securely inplace. mi

2.
